Renewed December 26, `1939 iociaims. (C1. 221-112) Our invention. relates to beverage dispensing 'devices andfhas particular reference to devices for'dispensing beverages o-f oth-erliquids in meas-I ured quantities.

, Our invention has for its, object to provide a dispensingdevice Witha valve which can be man- ,ually operatedv for delivering. a measured quantity of ka beverage such as cream from a container. For this purpose we provide a casing extending from the bottom of ther container and adapted to hold a .desir-ed quantity of the liquid.

The-.container has valvesontopand bottom,

. the casing when; the vupper valve is' closed for ref leasing the liquid through the lower valve.

Another object of our invention is to provider an interlocking. means between the valves so that' the/upper valve can be opened only after thelower valve'has beenclos'ed, and the lower valve can be opened only after thefupper valve has been closed.. This is accomplished in our device by providing. .a movable 'seat for the lower valve anda slidable member extending from the lower valve and vengaging. the' uppervalve so that by -raising the seatV thelower-y lvalveI isclosed and thenftheupper valve raised by the sliding member. sliding member so that the complete sequence of operation of the valves is automatically ef-y fected by the simple movement of a handle.

Another object of our invention is to provideVV a yieldablemeans to keep `the upper valve operi and thelower .valve closed, thereby practically eliminating any drip of the liquid ywhen thel valve is not used. This arrangement has an yadded ad.-4

vantage in that the chamber in thev casing isl always viilled and ready tobe 'discharged thereby expediti'ng the dispensing operations.

Our` invention is more rfully described in the which-v i.

,Our dispensing; device consistsv of avalve casing I fitted at the bottom of a container 2 hava jacket 3 on the outside, the space iny the jacket being lled withV a rock wool! or similar A jacketed cover 5 is provided ontop of the container.

The latter is engaged by the'middle 'portion of a handle I- 4which is suitably curved around the collar .so that it cannotslide lengthwise. The end portions of the handlev are retainednby T-'pieces I6 rotatively mounted on the 'endsyof a. bracket arms Il. eX- tending from a ring I8 ,threaded on the lower end oiv the tubular member I Z. A spring I9 keeps the handle in theraisedposition with the' tubular The ber I2 engages the valve II, pushing the rod Il) upward. I 1

The. rod has a valve.V l2l) at the upper end en -l gaging the lower end. of an air vent tube2 I; ex-4 tending to the top .of the container. The rodVv l0, being raised, seats the valve 2D and raises the valve 'Iyabove its seat. The valve. I remains thus raised by the action of the spring" I9 Whenthel handle. isleft free. As a result, the chamber '22 in the vcasing I is filled with the liquidA from the container, its escape being prevented by the valvey IIl whichis' seated onmthe tubular member I2'` The chamber 22 is made so that it holds adesired quantity'of the liquid as, for instance, one

ounce 'if ,the device is intended for dispensing cream into coieencups. This quantity of the liquid is ready to lbe delivered. For convenience handling the deviceitmay be mounted on .a

standard 23 extending from a suitable base (not shown). I y Whenit is desired to extract va measure of the liquid corresponding to the volume of the chamber 22, the handle I5 is depressed against the tensionv of the spring I9 until the front portion of the handle cornes to rest against the front T-piece I6. The valve] follows the `downward movement of the handle, being supported through the rod Ill on the upper end of the tubular member I2, until it comes to rest on the seat 6 thereby ,closing the chamber 22 from the container. With .the further downward movement of the handle the tubular member I2 leaves the valve I I and takes the position shown in Fig. .2,the sides.v of the valve seat forming continuation of the tapering sides off the bottom portion of the chamber 22 so that the liquid `can freelyflow from the chamber through the hole .24 in the tubular chamber I2 into a suitable receptacle placed under the valve. The red Il! slides by gravity downward. until the valve 2t comes to restvagainstthe upper' edge of the stem 8 thereby opening the lower end of the airvent tube 2I for admitting air through ducts 25 into the chamber 22. As a result, `the liquid rapidly escapes from the chamber 22 into the receptacle.

Upon release of the handle it is pulled upwardY mally rests at both ends on the T-pieces'I. Withv this arrangement the chamber 22 normally remains closed, the lower `valve II being then opened so that the chamber 22 remains empty.

In order to deliver a measured quantity of thel liquid, the handle I5 is raised thereby admitting the liquid into the chamber 22, and then re-y leased again, closing the upper valve l and opening the lower valve II as shown in Fig. 3;

This arrangement of the valves has an advan-k tage that there is practically no drip from the valve when it is not used because only anarrow and relatively short hole 24 remains open at the bottom, and the liquid cannot flow from this hole because it is closed on top by the valve I I.f Another advantage results from vthe fact that the chamber 22 is always lled withthe liquid so that it can be quickly emptied. The dispensing operation can be quickly and `conveniently performed using but a single hand, by holding a receptacle between the ngers and using one nger to de- A press the handle. l

`It should be noted that every time the valve I i is opened, the air filling the chamber 22 is allowedl to escape through the liquid in the container 2.

The bubbles of the air, rapidly rising through .the-

liquid, stir the latter and help to maintain uniform consistency.

It is understood that our device can beY further its modied within the scope of the appended claims.V
